Ford US did some funny things in the 70s, they put 400s into cars as well as F-series, so you'd think theyd've shoehorned the 300 into a large car (using this same approach) but no... These big block 6s only went into trucks, industrial vehicles, pumps, airport tugs, etc. so maybe the mounts will pose a bit of a problem going into a Falcon. The length could be another problem: they're at least 2" longer than a crossy. Probably comparable to a Chrysler hemi 6, with both having similar bore sizes, thus spacing.
